Geological disasters in mines, ecological environment and geology and geomorphology are closely bound up with each other. To reduce or avoid economic loss and to decrease the threat degree of geological disasters to life safety, the protection of geological environment are formulated in this study. Specifically, this includes taking mines that are dominated by thin bedded carbonate as the research objects. The goals of this study include prevention and control of geological disasters and protection of geological environment. The data are based on characteristics of geological strata in mines collected by the exploration, and combined with the characteristics of geomorphic environment, relevant rules aiming at the prevention and control of geological disasters. Then, pursuant to the selection of indicators, an evaluation system is constructed to verify the effectiveness of measures and strategies proposed, in which the score value is converted into the corresponding level to test the implementation effect of the measures and strategies proposed. Through comparing the changes of the utility levels before and after the implementation of measures and strategies proposed, it can be seen that the geological disaster levels of the five mining areas in the study region are respectively improved from the non-ideal levels V, IV, V, V, IV to II, I, I, II, II, with the tailings pond leakage times less than 4 times and collapse volume less than 5m3. And, the levels of geological environment are upgraded from levels IV, IV, IV, V, V to ideal levels II, II, II, I, II, accomplished by the vegetation coverage rate of the mine reaching more than 35%, as well as the recovery rate of exploitation and utilization rate of tailings both exceeding 85%, which indicates that the protection strategy proposed in this paper has good practicality and feasibility.

A liner conference, as a self-regulation organisational form of liner shipping companies, constitutes a typical "hard-core cartel" with significant anti-competitive effect. One of the main three trade routes of liner shipping traffic is the Europe-Asia Trade, on the two ends of which both the European Community (EC) and the Peoples Republic of China (PRC) play important roles in the international liner shipping market. However, the competition regimes on liner conferences in both jurisdictions are not equivalent. From a comparative point of view, this book reviews the historical development of maritime policy and regulatory legislation in the EC and the PRC, catches insight into the system of regulation regime and individual provisions in substantive and procedural meaning, and finally put a perspective into the future competition regulation in respect of the latest developments in both jurisdictions.

AbstractInformation technology and e‐commerce enable websites to provide personalized services based on consumer information, thereby providing convenience to consumers. However, the collection and use of consumer information may trigger concerns regarding privacy invasion. Grounded in exchange theory, the current study constructs a framework that links web personalization to consumer decisions (i.e., website loyalty and purchase intention) through consumer trust and reactance. The study also uses reactance theory as the theoretical basis to examine the moderating role of privacy concerns. An online survey was used to assess the effect of web personalization on consumer loyalty. The results show that consumers' privacy concerns negatively moderate the relationship between web personalization and website loyalty, and the influencing mechanism differs according to the levels of privacy concerns. More specifically, when consumers are less concerned about privacy, web personalization strengthens consumer trust to enhance loyalty. When consumers are more concerned about privacy, web personalization affects their loyalty through psychological reactance. The study findings show that although personalized services provide convenience to consumers, websites should carefully consider consumers' privacy issues. The trade‐off between web personalization and privacy concerns is necessary for a website's success.

AbstractThis study uses four sets of data from China Fertility Surveys completed during the years 1997–2017 to analyze the trend of induced abortion, with a focus on the twenty-first century. Married women of reproductive age who had a history of pregnancy during the 5 years prior to participating in a survey were the research object. The study also examines the variation of abortion proportions among different subgroups during different time periods, including an examination of the number and gender of children, place of residence, and contraceptive use of women who had induced abortions. The results show that the occurrence of induced abortion has decreased gradually, and that the risk of induced abortion was higher for those who had given birth to fewer children. However, induced abortion among women with two children has increased in recent years. It is noteworthy that induced abortions among childless premarital women have continued to increase in recent years, and that the sexual and reproductive health problems of adolescents remain of great concern. The occurrence of induced abortions after childbirth increased for those with one or two children, showing that the unmet need for contraception after childbirth should receive more attention. In addition, sex-selective abortion has been decreasing gradually, but still exists today.
